GRAIN-CAR DOOR.

Specification of Letters Patent.

Patented Aug. 24, 1909.

To all whom it may concern.'

Beit known that i, PETER J. A. Sonnoon, a citizen of the United States,and a resident of Holstein, in the county of Ida and State of Iowa, havemade certain new and useful improvements in Grain-Car Doors, of whichthe following is a specification.

My invention relates to improvements in doors and is especiallyapplicable to doors of grain cars, and it consists in the constructions,arrangements and combinations hereinafter described and claimed.

An object of my invention is to provide a door which will meet theseveral requirements in loading or unloading` grain and which can beconveniently manipulated to form openings of more or less extentaccording to the use to which the car is to be put.

A further object of my invention is to provide a device which may bereadily attached to the door of an ordinary car, thereby changing thelatter into a grain car with exceptional facilities for loading andunloading grain.

Further objects and advantages will appear in the followingspecification and will be particularly pointed out in the appendedclaims.

My invention is illustrated in the accompanying drawings, in whichsimilar reference letters indicate the same parts in the various views,and in which- Figure 1 is a side view of a portion of a car providedwith my improved door. Fig. 2 is a view of the door from the inner sideof the car. Fig. 3 is an inner view of the door showing it in its raisedposition. Fig. 4 is a transverse section through the door of a car alongthe line 4-4 of Fig. 2. enlarged detail view of the roller and casing.Fig. 6 is a view of a modified form of door.

Referring now to Fig. 1 l have shown therein a car 1 provided with adoor opening 2 in the side thereof. Disposed in the door opening is adoor 3, which is suspended from a track 4 above the upper edge of thedoor opening by means of the telescopic hangers 5 and 5 as clearly seenin Fig. 2. The latter are arranged to slide in and out of the casings 6and 6 and may be adjustably secured at various heights by means of thepins 7 and 7 which are adapted to extend through the casing and to enterholes S and S in the telescopic members.

Fig. 5 is an Referring now to Fig. 5, in which the supporting roller isshown in detail, itwill be seen that the top of the telescopic member 5is pivotally attached to a yoke 9, in which is rotatably mounted a wheelor roller 10. The wheel 1() is arranged to travel back and forth on thetrack 4, which is secured to the side of the car 1.

In order to prevent the roller from leaving the track l extend one sideof the yoke to form a curved hook 9 a, which projects underneath therail of the track 4. On the outer side of the same yoke member l providea hook 11, which is arranged to receive a pin 12 adapted to enter anopening 13 in the member 5. The construction described crmits the member5 to swing outwardly w ien the pin 12 is withdrawn and to be lockedsecurely to the yoke when it is in contact with it as shown in Fig. 5.

The main door 3 is provided with an auxiliary door 14 which isconsiderably smaller in size and which is provided with the hinges 1'5to permit the door to be swung upwardly. The auxiliary door 14 mayV belocked by means of a bar 16 arranged to be engaged by a catch 17. Y

Centrally dis osed of the auxiliary door 14 at the bottom t iereof is around opening 18, which is closed by means of a door 19 having an innerflange 19a arranged to enter the opening 18. This small round door maybe locked by means of a bar and latch 2() as shown inthe drawings.

rlhe main door 3, besides being suspended upon the track 4, may belocked to the side of the car 1 by means of the shot bolts 21 and 21.These bolts are pivotally attached at their inner ends to a lever 22which is pivoted at 23 to the end of a handle 24 extending on the insideof the car. When the handle is turned the bolts are moved inwardly oroutwardly guided by the guide members 25 and 25. This arrangementprevents the door from being opened from the outside, but permits theready unlocking from the inside.

From the foregoing description .of the various parts the operation ofthe device can be readily understood. ln Fig. 1 the main door is shownin its closed position. It will be observed that there is a spacebetween the upper edge of the main door 3 and the top of the opening 2.

This space is provided for the purpose of filling the car. It may beclosed by means of an auxiliary drop-down door 26, shown in Fig. 6,which will permit the 'filling of the car in the ordinary manner andwhich will swing up to close the space between the main door and theupper part of the opening.

The auxiliary door 14 is for the purpose of unloading the car by meansof shovels in the ordinary manner, and it can be swung ontwardly andheld up in any convenient main ner while the unloading is taking place.The purpose of the door 19 is to provide means by which a suction pipecan be inserted for sucking up the grain into an elevator. This door hasa latch which is automatically locked when the door is shut. Theprovision of the shot bolts 21 and 21 forms means by which the main doorcan be held securely. In order to permit the removal of the doors fromthe opening 2 I have arranged the telescopic members heretoforedescribed. By means of these telescopic hangers the door can be elevatedas shown in Fig. 3, the pins 7 and 7 being placed in the proper openingsin the telescopic members 5 and 5. rthe provision of the track 4 permitsthe door to be slid to one side. At times it may be neeessary to liftthe door out of the way and in order to accomplish this I have providedthe hangers shown in Fig. 5 and already described. In order to suspendthe door the pins 12 are withdrawn and the door may be ifted andattached to the top of the car by any convenient means where it willthen be out of the way to permit the loading of the car with materialswhich might otherwise injure the door. t

I am aware that other forms of the device based upon the same generalidea might be made but I consider as my own and desire to claim, allsuch modifications as fairly fall within the spirit and scopey of theinvention.

I claim- 1. The combination with a grain car provided with a dooropening, of a door therefor adapted to cover said opening, a trackdisosed above the door opening, telescopic iangers carried by the door,vokes pivoted:

to said hangers, wheels carried by said yokes and arranged to run onsaid track and means for locking` said hangers to said. yokes.

2. The combination with a grain car provided with a door opening, of adoor therefor adapted to cover said opening, a track secured above thedoor opening, telescopic hangers carried by the door, yokes pivoted tosaid hangers, wheels carried. by said yokes below the pivotal connectionwith the hangers, and arranged to run on said tracks, hooks secured tosaid yokes and arranged to eX- tend underneath the tracks for holdingthe rollers to the latter and hooks carried by the yoke for locking thehangers.

3. The combination with a grain car door provided with a door opening,of a door therefor adapted to cover said opening, a track secured abovethe door opening, telescopic hangers carried by the door, said hangersbeing provided with openings, yokes pivoted to said hangers at theirupper ends, wheels carried. by said yokes below the pivotal connectionwith the hangers and arranged to run on said track, hooks secured to thesides of the yokes and pins arranged to engage said hooks and. to extendinto the openings in said hangers for lockingI the hangers to the yokes.
